Intelligent Trash Can

Postby soublele » Mon Jun 04, 2012 12:21 am

Currently I'm working on this project whereby the trashcan will be able to detect the type of trash thrown (paper,plastic,metal) and able to segment it accordingly.

Besides, it comes with side features such as the trashcan will move to the user when signaled, auto open lid when hand motion is detected, sense when the trashcan is full.

I'm not particularly sure that its achievable in time for me. Therefore, I'm seeking for help here :|
Especially on the detection of type of trash.

All inputs are highly appreciated n welcomed.

so far after some decent research, there's two ways to detect the material.

First is through LDR whereby aluminium will reflect the light, glass will allow the light to penetrate through it and for paper, the light will pass through partially. Not sure whether the end result will be accurate or not.

Second is via image processing and border detection. This is quite complicated and i'm not sure i'll be able to carry this out.

Any ideas from sifus here? :D
